The lieutenant and commander

by Basil Hall

But of all the ingenious native contrivances for turning small means to good account, one of the most curious, and, under certain circumstances, perhaps the most useful, is the balsa, or raft of South America, or, as it is called on some part of the coast, the catamaran. The simplest form of the raft, or balsa, is that of five, seven, or nine large beams of very light wood, from fifty to sixty feet long, arranged side by side, with the longest spar placed in the centre. These logs are firmly held together by cross-bars, lashings, and stout planking near the ends. They vary from fifteen to twenty, and even thirty feet in width. I have seen some at Guayaquil of an immense size, formed of logs as large as a frigate's foremast. These are intended for conveying goods to Paita, and other places along-shore. The balsa generally carries only one large sail, which is hoisted to what we call a pair of shears, formed by two poles crossing at the top, where they are lashed together. It is obvious that it would be difficult to step a mast securely to a raft in the manner it is done in a ship. It is truly astonishing to see how fast these singular vessels go through the water; but it is still more curious to observe how accurately they can be steered, and how effectively they may be handled in all respects like any ordinary vessel.

The method by which the balsas are directed in their course is extremely ingenious, and is that to which I should wish to call the attention of sailors, not merely as a matter of curiosity, but from its practical utility in seamanship. No officer can tell how soon he may be called upon to place his crew on a raft, should his ship be wrecked; and yet, unless he has been previously made aware of some method of steering it, no purpose may be answered but that of protracting the misery of the people under his charge. Nothing can be more simple, or more easy of application, than the South American contrivance. Near both ends of the centre spar there is cut a perpendicular slit, about a couple of inches wide by one or two feet in length. Into each of these holes a broad plank, called guaras by the natives, is inserted in such a way that it may be thrust down to the depth of ten or twelve feet, or it may be drawn up entirely. The slits are so cut, that, when the raft is in motion, the edges of these planks shall meet the water. It is clear, that if both the guaras be thrust quite down, and held fast in a perpendicular direction, they will offer a broad surface towards the side, and thus, by acting like the leeboards of a river-barge, or the keel of a ship, prevent the balsa from drifting sidewise or dead to leeward. But while these guaras serve the purpose of a keel, they also perform the important duty of a rudder, the rationale of which every sailor will understand, upon considering the effect which must follow upon pulling either up the guara in the bow or that in the stern. Suppose, when the wind is on the beam, the foremost one drawn up; that end of the raft will instantly have a tendency to drift to leeward, from the absence of the lateral support it previously received from its guara or keel at the bow; or, in sea language, the balsa will immediately "fall off," and in time she will come right before the wind. On the other hand, if the foremost guara be kept down while the sternmost one is drawn up, the balsa's head, or bow, will gradually come up towards the wind, in consequence of that end retaining its hold of the water by reason of its guara, while the stern end, being relieved from its lateral support, drifts to leeward. Thus, by judiciously raising or lowering one or both the guaras, the raft may not only be steered with the greatest nicety, but may be tacked or wore, or otherwise directed, with precision.

I never shall forget the sensation produced in a ship I commanded one evening on the coast of Peru, as we steered towards the roadstead of Payta. An immense balsa was dashing out before the land-wind, and sending a snowy wreath of foam before her like that which curls up before the bow of a frigate in chase. As long as she was kept before the wind, we could understand this in some degree; but when she hauled up in order to round the point, and having made a stretch along-shore, proceeded to tack, we could scarcely believe our eyes. Had the celebrated Flying Dutchman sailed past us, our wonder could hardly have been more excited.

It will generally be found well worth an officer's attention to remark in what manner the natives of any coast, however rude they may be, contrive to perform difficult tasks. Such things may be very simple and easy for us to execute, when we have all the appliances and means of our full equipment at command; but, as circumstances may often occur to deprive us of many of those means, and thus, virtually, to reduce us to the condition of the natives, it becomes of consequence to ascertain how necessity, the venerable mother of invention, has taught people so situated to do the required work. For example, it is generally easy for a ship of war to pick up her anchor with her own boats; but it will sometimes happen that the launch and other large boats may be stove, and then it may prove of consequence to know how a heavy anchor can be weighed without a boat at all.

We happened, in his Majesty's ship Minden, to run upon the Coleroon shoal, off the mouth of the great river of that name, about a hundred miles south of Madras. After laying out a bower anchor, and hauling the ship off, we set about preparing the boats to weigh it in the usual way. But the master-attendant of Porto Novo, who had come off to our assistance with a fleet of canoes and rafts, suggested to Sir Samuel Hood that it might he a good opportunity to try the skill of the natives, who were celebrated for their expertness in raising great weights from the bottom. The proposal was one which delighted the Admiral, who enjoyed everything that was new. He posted himself accordingly in his barge near the spot, but he allowed the task to be turned over entirely to the black fellows, whom he ordered to be supplied with ropes, spars, and anything else they required from the ship. The officers and sailors, in imitation of their chief, clustered themselves in wondering groups in the rigging, in the chains, and in the boats, to witness the strange spectacle of a huge bower anchor, weighing nearly four tons, raised off the ground by a set of native fishermen, possessed of no canoe larger than the smallest gig on board.

The master-attendant stood interpreter, and passed backwards and forwards between the ship and the scene of operations—not to direct, but merely to signify what things the natives required for their purpose. They first begged us to have a couple of spare topmasts and topsail-yards, with a number of smaller spars, such as top-gallant masts and studding-sail booms. Out of these they formed, with wonderful speed, an exceedingly neat cylindrical raft, between two and three feet in diameter. They next bound the whole closely together by lashings, and filled up all its inequalities with capstan-bars, handspikes, and other small spars, so as to make it a compact, smooth, and uniform cylinder from end to end. Nothing could be more dexterous or seaman-like than the style in which these fellows swam about and passed the lashings; in fact, they appeared to be as much at home in the water as our sailors were in the boats or in the rigging.

A stout seven-inch hawser was now sent down by the buoy-rope, and the running clinch or noose formed on its end, placed over the fluke of the anchor in the usual way. A couple of round turns were then taken with the hawser at the middle part of the cylindrical raft, after it had been drawn up as tight as possible from the anchor. A number of slew-ropes, I think about sixty or seventy in all, were next passed round the cylinder several times, in the opposite direction to the round turns taken with the hawser.

Upwards of a hundred of the natives now mounted the raft, and, after dividing themselves into pairs, and taking hold of the slew-ropes in their hands, pulled them up as tight as they could. By this effort they caused the cylinder to turn round till its further revolutions were stopped by the increasing tightness of the hawser, which was wound on the cylinder as fast as the slew-ropes were wound off it. When all the ropes had been drawn equally tight, and the whole party of men had been ranged along the top in an erect posture, with their faces all turned one way, a signal was given by one of the principal natives. At this moment the men, one and all, still grasping their respective slew-ropes firmly in their hands, and without bending a joint in their whole bodies, fell simultaneously on their backs, flat on the water! The effect of this sudden movement was to turn the cylinder a full quadrant, or one quarter of a revolution. This, of course, brought a considerable strain on the hawser fixed to the anchor. On a second signal being given, every alternate pair of men gradually crept up the spars by means of their slew-ropes, till one-half of the number stood once more along the top of the cylinder, while the other half of the party still lay flat on the water, and by their weight prevented the cylinder rolling back again.

When the next signal was given, those natives who had regained their original position on the top of the cylinder threw themselves down once more, while those who already lay prostrate gathered in the slack of their slew-ropes with the utmost eagerness as the cylinder revolved another quarter of a turn. It soon became evident that the anchor had fairly begun to rise off the ground, for the buoy-rope, which at first had been bowsed taught over the stern of our launch, became quite slack.

I forget how many successive efforts were made by the natives before the anchor was lifted; but, in the end, it certainly was raised completely off the ground by their exertions alone. The natives, however, complained of the difficulty being much greater than they had expected in consequence of the great size of our anchor. In fact, when at length they had wound the hawser on the cylinder so far that it carried the full weight, the whole number of the natives lay stretched on the water in a horizontal position, apparently afraid to move, lest the weight, if not uniformly distributed amongst them, might prove too great, and the anchor drop again to the bottom, by the returning revolutions of the cylinder. When this was explained to Sir Samuel Hood, he ordered the people in the launch to bowse away at the buoy-rope. This proved a most seasonable relief to the poor natives, who, however, declared, that, if it were required, they would go on, and bring up the anchor fairly to the water's edge. As the good-natured Admiral would not permit this, the huge anchor, cylinder, natives, launch, and all, were drawn into deep water were the ship lay. The master-attendant now explained to the natives that they had nothing more to do than to continue lying flat and still on the water, till the people on board the ship, by heaving in the cable, should bring the anchor to the bows, and thus relieve them of their burden. The officer of the launch was also instructed not to slack the buoy-rope till the cable had got the full weight of the anchor, and the natives required no farther help.
